Thermoelectric Properties and Densification Behavior of SrTiO3/TiB2 Composites

Article Preview

Abstract:

The establishment of rapid synthesis process at a low temperature of thermoelectric non-doped and Y-doped SrTiO3 was tried by using the polymerized complex process and the pulsed current heating method with addition of TiB2 powder. The TiB2 addition was quite effective for reduction in the electrical resistivity of the thermoelectric SrTiO3, and the power factor of the Sr0.9Y0.1TiO3/TiB2 composite was similar to that of the Sr0.9Y0.1TiO3 polycrystal synthesized by the conventional solid state reaction method. It was also found that the addition of TiB2 significantly reduced densification temperature during sintering. This rapid consolidation caused by TiB2 addition was available even when the composite powder was sintered by conventional hot pressing.
